To all whom it may concern:

Be it known that I, WiLuaM JONATHAN Nmoio. a citizen of the UnitedStates re- -siding at Madisomiu the count of 15am! and State ofWisconsin, have invented a new and useful Improvement in Type-WritingMachines, of which the following is a specification.

The resent invention is a branch or divisicn n that more broadlyclaimed'in my divisional application filed March 30, 191), Serial No.687.463, and also is included within the generic invention which isdescribed and claimed in my co-pending a plication filed April 20. 1908,Seria 0 428.212.

The objects of my invention are first, to give the operator of thetypewriting machine a signal whereby he may know that the bottom of thepaper sheet is near; and second. to indicate to him the distanceremaining to the bottom of the said paper sheet from the currentprinting point, during the later sta es in the progress of the sheet. Iattain tiese objects by the mechanism illustrated in the accompanyingdrawlogs, in which-- "igure I is an end view of a aim is embodimentof myinvention; Fi I is a view of certain details thereof; ig. III is a frontview with the end of the carria in vertical section on the line A A,Fig. with the paper sheet removed and with the indicator 6 turnedone-fourth of a revolution in order to bring the orbital paperfeeler 8into a position where itv can be more clearly represented: Fig. IV is anend view ofn second embodiment. view of certain portions 0 the same, insection on the line (7 .l. of Fig. IV.

Referring to the several figures --A 01'- tion of the machine frame isindlcat at 10, and at l is shown a portion of the usualtransversely-moving carriage-frame, in the ends of which latter isjournaled the arbor 19 of the platen 11, as usual. The platen is rotatedin practice by line-space mechanism not necessary to be shown herein.

At 8 is shown the paper-table, .and at 81 the curved paper-fingers forholdin -the paper to the periphery of the dplaten. eae parts may be 'ofany approve t pa.

lliinventimt provides an in icstor that Fi V is a front n'ormall.revolves synchronously with the laten, ut which under conditions ofintererence' may remain stationary at a constant. point in itsrevolution until the end of the paper sheet reaches a certain constantdistance from the current printing point, the indicator thereuponresumin its revolving movements, and indicatin t enceforth the relativeposition of the on of the sheet.

The indicator may take various forms. In Figs. I and III will be. seen,at the end of the platen, a friction-wheel consisting of a passiverevoluble section, an active revolving section, and means for adjustingthe tension between the two. By passive I intend to convey the idea thatthe part which I term a passive revoluble section is the recipient offorce by which it is propelled, z'. e., it is the driven part of thesaid friction-wheel. B active is intended to be expressed the i ea thatthe active revolving section acts as the driver in communieatingmovement of revolution to the section rst mentioned. The passive sectionis the indicator 6. The active section is shown as a collar 13, formedwith a radial flange 13" and fitted upon the platen arbor 12, andrevolving as a unit with the platen 11; and the passive section consistsof an annulus mounted upon said collar and making contact bv the innerside face thereof with the said flange. The said passive sectionsustains lig t frictional en agement with the active section throu h t 0normal friction of the wearing our aces, and through the adjustabletension im nrted by the pieces 7 and screws 9. The rictional engs mentis intended to be extremely light-on y sufticient to cause the passivesection to turn simultaneously with the platen under normal conditionsof non-interference.

The means whereby the indicator is stopped at a constant point duringcertain stages in the progress of the paper sheet, may be most eels: yexfilained b making reference first to Figs. II, and II. The indicatorhere beats the radial extension piece 82 and the laterally-extendingrodtlte orbitaLpaper-feeler 8. The pa r-table 8 is suppli with alaterally e'xten ing slot 4. In the absence of the sheet 2, paper feelsr 8 revolves without interference in its orbit 5, passing thepaper-table through the till slot 4, its path thus intersecting the pathtaken by the aper-sheet- 2 down the face of the paper-tab e 8. When,however, a sheet of aper lies upon the paper-table, as shown in ig. I,the slot 4 is closed thereby, the movement of the paper-feelc'r isarrested by the sheet, and the indicator bearin said paper-fecler isbrought to a stop un ii the en of the paper sheet passes the slot. Inthe illustrations I show how the indicator may be made to bear theorbital paper-feeler in duplicate, in order that a paper-feeler mavnormally pass through the slot 4 at car half revolution of the platen,the peripheral indices being duplicated to correspond. For an but. smallwork like library card writing t e duplication would not be made.

The advantages of using a aper-feeler of the form shown in Fi s. I, IfiIII, in the case of a mechanism emp oying an indicator or controllingmember similar to the member 6, are, first, that thereby sheet-insertionis facilitated, the paper-feeler never being :11 a position to obstructthe entering of a new sheet into the machine. If in some chance positionof the mechanism the paperfccler s ould lie too near the paper-table topermit of sheet-insertion between it and the paper-table, the sheetcould be inserted above the paper-feeler 'ust as well. The paper-feelerwill eventually come into sheetcontrolled position whatever its startingrelation to the sheet. Second, in case of backing-up movement after therelease of the paper-teeter by the sheet, the backing-up mttom edge ofthe sheet will encounter a minimum of obstruction from such apaperfeeler, if indeed any at all, and even if the sheet-end is pickedup by the aper-feeler it will be released almost instant y thereb thespeed of the backin -up paper-feeler ein greater than that. o the platensurface and t ierct'ore than that of the backing-up sheet, as will heunderstood. Third, when the mechanism is backed-up from the position ofarts shown in Fig. I, the paper-feeler un er the actuation of thebaekwardly-turning platen recedes from contact with the sheet, so thatthe most delicate sheet may be backed up at any time without danger ofclogging. Fourth, the broadside presenta tion to the sheet of such a paer-feeler constitutes in some of the embo iments of my invention adistinct advantage, since thereby the pressure is more evenlydistributed upon the sheet. Sacha construction also a ords a convenientmeans for extending the workin ortion of a paper-feeler inward towar t ecenter of the sheet past the rinting margin as far as may be desired.

here are other advantages in the construction shown for-a mechanism ofthis character. It is not essential that such a paperfeeler be givenorbital movement intersect- 1,oos,es 1

ing the papenpath, nor is the portion of my invention invo via the formof the paperfeeler necessarily Iimited to the use of a paper-feeler ofthe exact type or construction shown.

It will be borne in mind that the interference of the paper sheet stopsthe indicator at a constant point in its revolution, or at a pluralityof constant points. It follows that it is iven movement thereafteralways from a re atively constant startin point. The pointer or index 34(Fig. III) is attached conveniently to one of the paper-fingers 31. Ican mark with the indicating mark 0 that point on the periphery which isopposite the pointerwhen the art 6 is in its arrested position. The mar0 must obviously remain opposite the pointer until the memberti resumesits revolving movement. As the member 6 resumes its movement the momentthe bottom edge of the sheet clears slot 4, and as it then moves forwardsimultaneously with the laten, and thereafter withthe sheet, the s eetbeing fed by the platen, it is plain that if I mark the next stoppingpoint 9 to correspond with thedistance at that moment from the printinpoint to the end of the sheet, which we wfil say equals ninedouble-spaced lines, I can mark the succeeding stoppin -point 8, and soon down to 1 and the en of the sheet.- Or, if it be desired to space bysingle lines, the first stopping-point after 0 could be marked say 19.the next 18, and so on down to 1. Or, other indicating units could beused. I have now a means of informing the operator of the exact extentof his remaining bottom margin at any point within the range of mydevice. I could mark my periphery to indicate the distance to the lastline intended to be rinted upon the sheet, just as well.

n indicator marked as I have described satisfies both the objects of myinvention in what I regard as the most perfect manner. but I consider myinvention sufliciently br ad to include within its scope various knowntypes of indicating or signaling devices, either visual or audible,which may prove suitable and convenient for use in practical embodimentsof the main prineiples of the invention. I regard the murin surface asconstituting an odor uate signa l to the operator; and in addition itinforms him of the exact position of the bottom of the sheet.

Itis to be noted that the passiverevoluble. section of the indicator mayvary more or less in character and construction in 'prao tice, and themeans and mannerof actuating the same may vary. In Figs. I, II and Ill lhave shown the same in the form of a ring, "annulus, or, as it mayenericallv he termed, band. The radial thickness of the said band mavvary in raetice.

In Figs'lv and V t e friction-wheel of u the pa .ihe said lateral whichthe indicator constitutes the passive section 6 is divided verticallupon the friction line 35-35, instead of orizontally, and the tension isadjusted differently; namely, by means of the screw and t e spring 24.The indicator here is shown as revolvin upon an axis 29 separate fromthat of the p aten. The said axis is constituted by a laterallv-extendedshouldered axle or stud. carrie by the frame-extension or bracket 19upon the carriage-frame 1. In order that the normal movements of theindicator may be synchronized with the revolving movements of the laten,I show the active section of the riction-wheel as a toothed wheel 28,meshing with the toothed wheel 22 keyed to revolve with the platenbutany equivalent train of parts would answer the purpose. The saidindicator or revoluble member 6 and the said toothed.

wheel 23 are separately mounted to rotate upon axle 29, the spring 24attached to the ltlll'lll e-frame 1 serving to press them intolateraFfrictional enga ement. The tension of such spring, and t efrictional engagement. are regulated by the ad'usting screw 25. asindicated above. The in ex or pointer 34 is attached to the axle or stud29.

In Figs. IV and V the orbital paperfccler 26 may be a fixed rojectioncarried by the indicator; but I sliow it as pivoted upon the pin 80carried by yoke 36 attached to the indicator. so as to be able to bendidly backward in the contingencv of a backingup movement of the persheet. The

orbital pa ier-feeler '3 in l ig. I, intersects the path 0 the apersheet, assing through the slot 4' in t e aper tabYe 8; and when the slotis (lOsQtl liy the aper sheet 2 as shown. the paper-feeler 26 cannotcomplete in movement and stops the indicator until ihe bottom of the par sheet passes the slot. The yoke 36 is attac led to the revolubleindicator 0 so as to rotate therewith and exn-nda inward therefrom, tofurnish a convenicnt support for the paper-teeler at a distance inward(mm the edge of the sheet. The pin 80. upon which the paper-feeler inivoted oi' hinged, is mounted on the said yoke at a point eccentric tothe axis of the yoke. and provides the paper-feeler with a secondaryaxis upon which it has movement relative to its carrier. The movement ofr-feeler upon this secondary axis in limit by its contact with thelaterally-extending portions of the voke. 86. sothat it wil notcompletely revo ve on the pin 80. but will be stopped by one or theother of v-extending portions. Contact with one of these portions givesit the extended position shown in Figs. IV and V. in which it isetlective to en ge with the sheet, and in which it is e ective in thepresence of the sheet to detain the indicator ath' here of the paper-feeer 26 like that o the 6. When the end of the sheet passes thepaper-feeler the paper-feeler, no longer de tained bv the sheet, entersslot 4 in the paper-table, and the member 6, no longer detained by thepaper-feeler, is given simultaneous movement'with the platen ,under theimpulse of its frictional connection with wheel 23. If the sheet bebacked up after having released the paper-feeler, the backingup bottomedge thereof will meet the paperfeeler and bin e it idly backward on pin30 away from thedaterally-extendin ortion of yoke 36 that previouslycontrol e it, thus permitting free backing-up of the sheet rom alate'position. This acking-up provision is what might be termed aone-way joint, and it is not necessarily limited to a gaper-feelerhaving orbital movement.

acking-u from the position shown in Fig. IV is simi at to thatpreviously described in connection with pa er-feeler 3 of Figs. 1, IIand III, papereeler 26 likewisereceding from contact with the sheetunder the actuation of the backwardly turned platen.

Various modifications may be made in the construction and arrangement ofparts, etc. without necessarily involving any departure from the generalprinciples of the invention.

Althou h I show the indicator as the passsive revo uble section,suitably marked, of a friction wheel, because I regard that as the mostperfect form for it, it is to be understood that the claims are notnecessarily restricted in respect thereof, or in respect of a frictionalengagement between the indicator and the art that impels it, except inthe case of tliose claims which are express] limited thereto.

Alt ough I show the interscctin parts 8 and 26 as intersecting the pntliof t ie paper sheet at the paper-ta )le 8, it is to be understood thatthis is not essential in all cases.

The form which my invention would preferably take depends largely uponthe make of machine to which it is to be attached. That shown in Figs.I, II, and Ill, would be named first, because of its simplicity: but itwould be the most likely of the forms shown to interfere with feed rollmechanism under the )laten. That shown in Figs. IV and V .wou d be theeasiest to apply to machines already assembled.
